Simon,

Carbon nanotubes have an additional interesting property: the tube ends apparently have an extremely low "work function". They'll let loose electrons for the slightest provocation. Evidently they make nice low-temperature electron emitters. Diamond films have similar properties.

The technology was not mature when I looked at it, but could eventually make a nice cathode for Polywells.
